Abstract: The present disclosure pertains to a light sensing system configured to determine an amount of ambient light exposure experienced by a subject. The present invention wirelessly exchanges light information between different wearable devices of the same user and/or between devices of different users. Local and/or central light profile databases are built-up by the system and are shared between the devices so that light data that is typical for a location at a specific time of day and year can be used to estimate current ambient light levels for situations in which no measurement can be taken.

Abstract: Methods and systems pertaining secure transaction systems are disclosed. In one implementation, a computer with a verification token associated with a computer can send user authentication data as well as a secure datum to a control server. The verification token may obtain the secure datum from a validation entity. The control server can validate the secure datum and authentication data and can generate a payer authentication response.

Abstract: Systems and methods to estimate circadian phase of a subject use one or more sensors to track an activity level of the subject over a period. Actual light exposure need not be tracked nor used to estimate the circadian phase of the subject. One or more estimated light exposure parameters are based on the activity level. The estimated circadian phase is based on the one or more estimated light exposure parameters,possibly derived from activity measurements.

Abstract: Described herein are systems and methods in which more secure methods are provided for a connected device to conduct transactions. In accordance with embodiments of the disclosure, a transaction code is generated and provided to the connected device. The transaction code may be stored in association with the information for the transaction such that when the transaction code is received at a transaction processing server, the transaction processing server is configured to generate an authorization request that includes the transaction information. The authorization request may then be routed to an authorization server associated with an account maintained by the transaction processing server.

Abstract: The present invention relates to a light sensing system for sensing ambient light intensity, comprising a light sensing device with at least one light sensor and a calibration device for calibrating the sensor. The calibration device comprises at least one light source that emits light with a standard intensity. The invention is further related to a corresponding method for calibrating a light sensing device, comprising the illumination of the light sensor of the light sensing device with light that has a standard intensity, the comparison of the output intensity signal of the sensor with an expected signal that corresponds to the standard intensity, and the matching of the output intensity signal of the sensor to the expected signal by adjusting a gain parameter of the sensor.

Abstract: Embodiments of the invention are directed to systems and methods of user authentication for data services. The data services may include accessing a tax return at the IRS, accessing or completing a student loan application, accessing a credit report, etc. User authentication data is collected by a data provider and provided to a server computer, and user device data is collected by the server computer after the user device accesses a resource identifier (e.g., URL) associated with the server computer. The user authentication data and/or user device data is analyzed and a risk score is generated.

Abstract: The invention relates to an apparatus (100) and a method for generating a model output x(ti) describing a circadian rhythm of a person (P) at a time ti. In a preferred embodiment, a light sensor providing the photic exposure (L(ti)) and an activity signal (A(ti)) indicating the current level of activity of the person (P) at the time ti based on motion measurements (via an accelerometer) are used to calculate a wakefulness variable (?) that indicates if the person (P) is awake or sleeping. The wakefulness variable is then used to determine a driving term (N(t)) for a driven oscillator model (135) which simulates the model output x(t) under the joint influence of light and activity.

Abstract: Apparatuses, methods, and systems pertaining to the verification of portable consumer devices for 3-D Secure Systems are disclosed. In one implementation, a verification token is coupled to a computer by a USB connection so as to use the computer's networking facilities. The verification token reads identification information from a user's portable consumer device (e.g., credit card) and sends the information to a validation entry over a communications network using the computer's networking facilities. The validation entity applies one or more validation tests to the information that it receives from the verification token. If a selected number of tests are passed, the validation entity sends a 3-D Secure datum to the verification token. The verification token may enter the 3-D Secure datum into a hidden field of a Purchase Authentication Page appearing on the computer's display.

Abstract: The present invention discloses a method and signal processing device (620) for analyzing a ballistocardiogram (BCG). The actual energy content of the cardiac part of the BCG in a predefined time window is determined and compared with a reference value. A difference between the actual energy content and the reference energy content exceeding a predefined threshold is indicative of the presence of an arrhythmia in the evaluated part of the BCG because the force exerted by an arrhythmic ventricular contraction, if at all present, is typically substantially smaller than the force exerted by a ventricular contraction of a regular heartbeat. This insight facilitates a more accurate detection of the presence of arrhythmias in a BCG compared to BCG detection schemes based on a heart rate analysis.

Abstract: Information about a person's circadian rhythm is generated in terms of a difference between a reference and a specific circadian time for a specific wall-clock time or in terms of a difference between a special and a specific wall-clock time for a specific circadian time event.
